Abstract Thirty Devonian-Carboniferous Boundary sections of the Rhenish Slate Mountains and adjacent subsurface areas are reviewed with respect to litho-, event, conodont, ammonoid, sequence, chemostratigraphy. In interval from base uppermost Famennian (Wocklum Beds, Wocklumian) middle Tournaisian (base Lower Alum Shale), 11 conodont 16 ammonoid (sub)zones distinguished. The terminology Hangenberg Crisis Interval is refined, an overall regressive Prelude below main Extinction, which defines...
Petrophysical (gamma-ray spectrometry, magnetic susceptibility) and geochemical (X-ray fluorescence spectrometry inorganic carbon isotope geochemistry) methods are used for stratigraphic correlations palaeoenvironmental interpretations of the Devonian-Carboniferous boundary interval in northern part Rheinisches Schiefergebirge, Germany.Sections at Oese, Oberrödinghausen Drewer were studied range from Famennian Upper expansa Zone to Tournaisian Lower crenulata Zone.The Wocklum Limestone...
Abstract The Borkewehr section near Balve at the southeastern end of Remscheid-Altena Anticline is currently best and most complete Devonian/Carboniferous Boundary (DCB) succession Rhenish Massif, Germany. Based on a multidisciplinary approach, focusing refined conodont ammonoid biostratigraphy, microfacies analyses, sequence stratigraphy, carbon isotopes (C org C carb ), trace element geochemistry, including REE data, cyclostratigraphy, proposed as candidate for new basal Carboniferous...
Abstract The widely quarried and commercially exploited Gonioclymenia Limestone of the western southern Tafilalt Platform (Anti-Atlas, SE Morocco) represents a transgressive but strongly condensed shallowing upwards unit that overlies conformably or unconformably Famennian to Lower Devonian deposits. It is characterized by abundant, giant-sized speciosa , which characterizes V-B, rare Leviclymenia ramula sp. nov. Associated conodont faunas fall in Bispathodus costatus Subzone B. aculeatus (=...
Abstract A review of the literature shows that Famennian global Annulata Event(s) can be recognized as a transgressive, often hypoxic and eutrophic, interval interrupts an overall regressive eustatic trend in more than 40 regions North America, Europe, Africa, Asia Australia. According to differences palaeogeography, sedimentology biota, these occurrences are assigned 10 event settings. The first detailed data on facies, ammonoid conodont faunas presented for Rheris Basin eastern Anti-Atlas...
Abstract The Hagen-Balve Reef is one of the largest Devonian carbonate complexes in Rhenish Massif exposed many former or active, economically significant quarries, especially Hönne Valley region at its eastern end. timing and patterns reef drowning, final extinction, middle Frasnian to Famennian post-reefal facies history, including details global Kellwasser Crisis, were studied based on two boreholes (HON_1101 B102) outcrop Beul near Eisborn. More than 100 conodont samples provided a fine...
The provenance of top-Famennian sedimentary rocks linked to the Hangenberg Crisis from northern Rhenish Massif (Germany) was investigated by means detrital zircon U-Pb geochronology. Based on obtained age spectra, three main tectonothermal domains are recognized as possible sources: Paleo- and Mesoproterozoic (~ 2000–1000 Ma) units Baltica Early Paleozoic Caledonian orogen 500–400 Ma). Our interpretation detritus having been derived source areas, i.e., Scandinavian Caledonides, with a minor...
Abstract The Upper Devonian to Mississippian was a very dynamic time in Earth’s history and encompassed substantial changes widely separated palaeoenvironments. Major evolutionary trends did not occur through long-lasting interval of ecological stability, instead they took place as recurring global events and/or crises different magnitude, duration, intensity. Framed by two the most devastating intervals – Kellwasser Hangenberg Famennian has yielded other 2 nd 5 th order events/crises. Many...
Abstract A Late Devonian to (?)Early Mississippian section at Hushoot Shiveetiin gol in the Baruunhuurai Terrane of Central Asian Orogenic Belt (CAOB) exposes large parts cyclic Famennian shallow-water siliciclastic shelf deposits composed siltstones, sandstones, shales, volcaniclastics, and intercalated autochthonous carbonates. The youngest part section, possibly Early Mississippian, is represented by arkosic sandstones with plant remains. facies reflects a range from shallow-intertidal...
